To answer questions that have
different combinations of Roman numerals as
answer choices, you must evaluate each
Roman numeral separately in relation to the
question. Then, look to see which answer
choice corresponds to the numerals you have
selected.
Directions: Choose the letter that best answers the
question or completes the statement.

Questions 9–12 Each of the lettered choices below refers
to the following numbered statements. Select the best
lettered choice. A choice may be used once, more than
once, or not at all.
(A) Limiting factor
(B) Logistic growth
(C) Carrying capacity
(D) Exponential growth
(E) Population density
Students’ paragraphs will vary. All
should include mention of population density; carrying capacity; types
of growth; and limiting factors, both
density-dependent and densityindependent. Students should also
describe changes in the human population, drawing upon the text and
figures in Section 5–3 for support for
their descriptions. Using data in
Figure 5–14, students should note
that the projected population in
2050 is 9,078,850,714 and that the
growth rate in 2050 is projected to
be 0.43 percent annually, compared
with an average annual growth rate
of 1.23 percent in 2000.
Performance-Based
Assessment
Visuals will vary but should include
density-independent factors, such as
fire, seasonal cycles, and natural disasters, and density-dependent
factors, such as competition, predation, parasitism, and disease.
9. Birthrate = death rate
10. Slows the growth of a population
11. Number of individuals per unit area
12. Population grows at a constant rate
Your students can independently
test their knowledge of the chapter
and print out their test results for
your files.
